DISINTEGRATOR.

SPEGIFIOATION forming part of Letters Patent No. 705,796, dated July 29, 1902 Application filed Aprilfl'l, 1902.

and combinations of parts which constitute my improvement as applied to a disintegrator in which a revoluble beater operates in conjunction with a revoluble grinding-chain i her, asillustrated in the accompanying draw ings, in which- Figure l is a section taken through the line C D of Fig. 2 and looking from theleft of Fig. 2. Fig. 2 is a section through the casing and grinding-chamber on the line A B. Fig. 3 is a side elevation of the machine, showing the feeding-hopper. Fig. 4 shows a portion of one of the ring-plates Z, the serrations or teeth g on its inner concave edge, and two of the fan-blades f, fitted in notches r'in the annular rim at the edge from which the teeth project. Fig. 5 shows the grid-bars as seated upon the annular shoulders s s of thechamber sides in their spaced relation and which is maintained by the toothed rings seen in Fig. 4. Fig. 6 shows a portion of the chamber sides and the annular shoulders s s on the inner walls thereof on which the grid-bars e are shown seated and which are spaced and ed to fit between the grid-bars. Fig. 7 shows in section one of the toothed. rings and its notched rim 'r for holding the fan-blades.

Similar letters refer to similar parts throughout the "several views. Referring first to Fig.2, Ct a are the beaters, revolving at a high speed in the directioii shown by the arrow .90. They are carried by the shaft 0, running in bearings 70 70, so that the heaters overhang Within the casing h. Atta'chedto theshaft b, which ends in the form of a disk m, is the revolving grinding-chamber g, which also overhangs within "the easing it and in sucha-manner as to surround 50 the boaters a a. The heaters shown are pro-' secured by the ring-teeth g, which are adapt- Serial No. 1033587. (1% model.)

volves with the grinding-chamber, while the internal fan-beater is fixed'to and revolves on a separate shaft-section. Between these two separate revolving fans is the grid, and the two air forces coiiperate to keep the grindingchamber free of the material as itis reduced. The grinding-chamber is revolved in a direction opposite to that of the boaters and is provided at the sides with the serrated surface or teeth cl and at the periphery with the bars c, which are held so as to leave small spaces between their adjoining edges through which the ground material passes out of the chamber. Outside the periphery of the chamber and attached to the sides thereof a fan is provided which consists of the two rings Z Z, connected' together and to the blades or ribs f f by the bolts t, so that the action of the fan draws the air or finely-ground material out of the interior of the chamber and forces it around the casing to the outlet 0 and into a settling-chamber or other receptacle where it is required.

The feed side of the grinding-chamber is connected to the closed side by means of bolts t, which also secure the fan-rings Z Zto the sides of the grinding chamber. The rings forming the sides of the fan are serrated on their inner edges to 'form teeth like a saw edge, between which are held the bars e, forming the grid. These bars are held so as to leave spaces between them of a size to suit the fineness of, the grinding and can be renewed by removing the fan binding-ring plates.

In Fig. 4: is seen a portion of one of the toothed ring-plates, the teeth (1 of which are formed on its concave edge as the means for upon an annular shoulder s on the side wall of the grinding-chamber, and when so seatedare spaced and secured by and between the teeth q of the pair of rings Z. In Fig. 6 is seen the pair of toothed rings on the inner sides of the grinding chamber, a grid e, seated upon the annular shoulders s s and secured thereon by the toothed rings,and the notches 'r r being also shown in the ringrims to receive and confine the inner edges of the fan-blades f, the blade in this figure not being shown. It is important to note that while the bolts 25 clamp the fan-blades to and between the toothed rings the bolts also serve to clamp the latter to the sides of the chamber, as in Fig. 1. The teeth q and the notched side rims-r are better seen; in Fig. 7.

A feed-hopper 1- is arranged in theside of the casing, through which material is delivw ered within the circle of the open side of the grinding-chamber. It is immediately caught by the wing-beaters a, and it will be understood that the impact between the beaters a and the side teeth 61 of the chamber is very great, corresponding to a much higher speed than can be attained by boaters revolvingin a stationary chamber. When reduced to a fine enough degree, the material will be drawn by the action of the fan-blades from the chamber through the grids e and then forced around the casing to the outlet 0. The outlet may be as shown at 0 or in any other suitable position to suit the delivery required, and the material may be forced to a considerable distance by the power of the fan. The power of the air-current is increased by the spiral form of the outer casing, and in large machines or when using coarse grids additional inlets, such as are shown by dotted lines at u u, for air may be provided at the center of the casing, so that a free suction is obtained.

The shaft 1) runs in the bearings s s independently' of the shaft 0, and consequently the relative speeds of the grinding-chamber and of the heaters may be made to vary to any desired extent by altering the sizes of the driven pulleys c' and j, respectively. Usually I prefer to run the chamber at a slower speed than the beaters, and I therefore provide a larger pulley i on the shaft 5 than on the shaft 0. Collars are provided on the shafts b and c to prevent their movement longitudinally, and they are preferably run in self-oiling bearings; but as these form no part of the present invention they will not be further described.

The upper half of the disintegrator-casing is removable to allow of the insertion of the heaters and grinding-chamber,being connected to the lower half by flanges and bolts.

What I claimas my invention, and desire to secure by Letters Patent, is-

1. In a disintegrator and in combination, a fixed casing having a feed-inlet and a discharge, a revoluble grinding-chamber having circumferential openings and fan-blades fixed around and outside of the circumferential openings and revolving with the grinding-chamber, whereby the ground material is drawn from the chamber into the casing and ejected from the latter.

2. In a disintegrator and in combination, a fixed casing having a feed-inlet and a discharge, a revoluble grinding-chamber having circumferential openings,fan*blades fixed around and outside of the circumferential openings and revolving with the grinding chamber, and a revoluble fan-beater within the revoluble grinding-chamber, whereby the ground material is' both drawn and forced from the chamber into the casing.

3. In a disintegrator and in combination, a fixed casing having a feed-inlet and a discharge, a revoluble grinding-chamber, fan'- blades fixed to said chamber outside of and around its circumferential openings, a revo luble fan-beater within said chamber, and a circumferential grid between the external and the internal fan parts.

4. In a disintegrator and in combination, a fixed casing having a feed-inlet and a discharge, a revoluble grinding-chamber hav ing a circumferential grid of bars, a fan carried by the chamber external to its grid, and surrounding it, and means whereby the gridbars and their surrounding fan-blades are separately fastened together and to the side walls of the grinding-chamber.

5: In a disintegrator and in combination, a fixed casing having a feed-inlet and a discharge, a revoluble grinding-chamber having a circumferential grid of bars and means for spacing and securing the grid-bars consisting of a pair of ring-plates each formed with serrations or teeth on their concave edges by which the ends of the bars are spaced, and bolts bindingthe toothed rings upon the ends of the bars.

6. In a disintegrator and in combination, a fixed casing having a feed inlet and a discharge, a revoluble grinding-chamber having circumferential grid of bars, fan-blades fixed around and outside of the circumferential grid, and means whereby the grid-bars are spaced and together with the fan-blades are fastened between the side walls of the chamber, consisting of a pair of ring-plates, each formed with serrations or teeth on their concave edges between which the ends of the grid bars are spaced and bolts passing through the chamber-walls and through the toothed ring-plates binding the latter and the fanblades together upon the ends of the grid-bars.
